Maternity Services A local guide to routine antenatal care for healthy pregnant women and referral guidance for assessed risk in pregnancy Introduction This ‘aide memoir’ is produced as an additional resource to the ‘Pathways for Maternity Care’ national guidance document produced by NHS Quality Improvement Scotland (March 2009). It is designed to enhance the referral process when risk assessment indicates a deviation from accepted normal parameters. Continuous risk assessment, clear communication and documentation, promoting normality and supporting women’s choice are key to ensuring best midwifery practice. When a woman’s choice differs from the recommended care pathway, her choice should be supported in conjunction with a Supervisor of Midwives and clearly documented in her pregnancy records. The on call Supervisor of Midwives is available 24 hours via Labour Ward: 01896 826897 The content is not exhaustive and accountability for appropriate referral rests with the midwife whose knowledge and competence govern her clinical judgement (NMC Midwives Rules 2004, NMC The Code 2009). Any additional discussion between Midwife and Obstetrician should be documented on the ‘Record of Discussion’ sheet, and filed as indicated on the form.

Appropriate indications include: Previous or anticipated anaesthetic problems (e.g. failed intubation or regional analgesia, dural tap, pain during caesarean section) Severe back or neck problems BMI > 40 Women who decline blood products Severe drug reactions Specific advice at time of midwife booking Folic Acid (400μg/ until 12 weeks) or 5mg/day if increased risk (previous neural tube defect or anti-convulsant therapy) Teratogenic medication (urgent discussion or appointment with obstetrician) Thyroxine (increase dose by 25μg and check freeT4 and TSH as soon as possible after this) Ongoing risk assessment throughout pregnancy Where the following risks are identified in pregnancy, discussion with the on call Obstetric Registrar or Consultant is appropriate, or an appointment at a Consultant clinic. In more urgent cases, it may be appropriate to refer directly to Labour Ward or the Pregnancy Assessment Unit. Raised blood pressure or symptoms of pre-eclampsia - see page 00 Fundal height or clinical findings suggest small for gestational age - see ANC; if very small see in PAU Confirmed exposure to active viral infection when previously non-immune - phone registrar on call Malpresentation after 36 weeks – see at ante-natal clinic Abnormal αFP results or USS – see at PAU Chlamydia positive - phone registrar on call Consultant Led Care Medical disorders in pregnancy Those with the following medical disorders are suitable to book at Dr Campbell’s Clinic: Epilepsy Inflammatory Bowel Disease Coeliac disease Diabetes Previous or active thromboembolic disease Severe Asthma (needing oral steroids or recent hospital admission) HIV / HEP B / HEP C Alcohol / Drug Misuse Heart disease Major Psychiatric Illness Renal disease / Liver disease Severe anaemia / Haematological disease Connective Tissue / Autoimmune disease / Anti-phospholipids synd Multiple pregnancy Those with Twins (or other multiple pregnancy) should have a detailed scan appointment with Dr Magowan for between 11 – 14 weeks. For women where the identified risk is through family history, an appointment with the consultant should be made soon after initial booking. Significant Hereditary Condition in the family Known haemoglobinopathy, or known haemoglobinopathy trait and a partner who screens positive Past Obstetric History The following are suitable for consultant led care with whichever consultant is responsible for that geographical area: Previous Mid trimester loss / Previous Cervical suture Previous stillbirth / neonatal death Previous haemolytic disease / Rhesus disease Previous gestational diabetes Previous congenital abnormality Significant morbidity of baby Previous severe PIH / Eclampsia / HELLP Previous preterm labour Previous baby AFFECTED by Group B strep Previous severe / early onset IUGR (<34/40, <1.5kg) Previous Major Obstetric Haemorrhage (inc abruption) Where the following risks are identified during ongoing assessment in pregnancy, referral directly to the Consultant is appropriate: Placenta praevia Preterm rupture of membranes <37 wks Post term labour >42 weeks Significant or recurrent APH Obstetric Cholestasis Oligo or Polyhydramnios Haemoglobin < 9g/dl Platelets <150x109/l, repeat in 4 weeks. If falls to <100x109/l refer to ANC. If very low (e.g. <80x109/l) refer to on call Reg. Current active genital herpes Syphilis, Hepatitis B or HIV positive Abnormal Oral GTT (fasting >5.4mmol/l, 2 hour >9.0mmol/l) GENERAL INFECTION ADVICE Farm workers Toxoplasma (which causes miscarriage in cows and sheep), a chlamydia (which causes miscarriage in sheep), and listeria can all cause miscarriage in humans. Pregnant women should therefore avoid animal work, particularly in the lambing and calving seasons. Overalls and boots worn for work should be removed at the house door, and the boots cleaned and left outside. Soiled overalls should be placed directly into the washing machine by the wearer, who should then wash and dry their hands thoroughly. At the end of the season the lambing/calving shed should be thoroughly washed and swept out, and left open to the air for the summer. Handwashing by all who enter the house from the farm at any time is the key to controlling such infection. Nurses Nurses may be concerned about CMV, particularly if they are in contact with small children. Serology is of little benefit, as the presence of antibodies does not necessarily denote immunity. Hands should be washed well and often. The risk of CMV is very small. Travel and vaccinations Consider aspirin ± graduated compression stockings for long-haul flights. If the woman is visiting a malarial region, give advice on mosquito nets, wearing long sleeves and trousers (tucked into socks), insect-repellent spray, cream, wipes, etc. Antimalarials should be taken (Larium should be avoided if possible, although it may be safe >12 weeks). Refer to GP. The risk of vaccinations is likely to be extremely small. Pets There is a small risk of toxoplasmosis from cats. Women should wear household rubber gloves to clean litter trays and wash their hands afterwards. Better still, they could get someone else to do it! They should also avoid children’s sandpits and wear gloves for gardening. Adult dogs with no diarrhoea do not pose a significant risk. SPECIFIC INFECTIONS The risk of chicken pox infection causing harm to the baby in early pregnancy is very small. Give ZIG (Zoster Immunoglobulin) if < 10 days from contact or < 4 days from onset of rash if the mother was VZ negative on booking bloods. Severe and even fatal cases of chickenpox can occur in neonates whose mothers develop chickenpox from 7 days before to 1 month after delivery (usually 2 days before to 2 days after). The baby should be given varicella zoster immunoglobulin (VZIG) as soon as possible if maternal symptoms develop. VZIG may be given to babies in contact with chickenpox whose mothers have no history of chickenpox (or no antibodies on testing). Group B β-haemolytic streptococci (GBS) Antenatal screening is not indicated in the UK (initial screen positives may become negative, and vice versa). There is no evidence to support antenatal treatment of asymptomatic carriers, as carriage is rapidly re-established following treatment. Intrapartum prophylaxis is probably appropriate for: Those found with GBS on vaginal culture during this pregnancy Those who have had a previous baby affected by GBS Those found to have GBS bacteriuria during pregnancy Prophylaxis is probably not appropriate for: Those found incidentally to have had GBS in a previous pregnancy, or when not pregnant. Parvovirus B19 This causes slapped cheek syndrome in children and adults. If a mother develops slapped cheek syndrome before 20 weeks gestation, the baby can become profoundly anaemic and hydropic. This anaemia can be treated with intra-uterine transfusions. There is probably no fetal risk beyond 20 weeks. Infection at any stage does not cause fetal abnormality. If contact significant (with someone who had or has since developed a rash within 48 hrs and was in face to face contact for > 5 minutes or indoors for >15 minutes) refer to clinic, registrar or PAU for advice.
